British Airways cabin crew are planning a series of five-day strikes, unless BA enters into "meaningful negotiations" over cost cutting measures.
The first strike is due to begin on 18 May, ending on 22 May, with further five-day strikes beginning on 24 May, 30 May and 5 June.
BBC News website readers have been explaining how industrial action would affect them.

MELISSA SWAIN, PRESTON
I'm going to New York to complete a two month internship which I have spent a lot of time and money organising.
This is an incredible opportunity for me - to work in the film and TV industry - and I'm very concerned that after everything I've done to plan this trip, it will be ruined by my flight being cancelled.
I'm due to fly from Manchester to New York connecting at London Heathrow with BA. I am praying that my particular flight plans are not affected by the strike.
All of my savings have gone into this venture and, as a graduate with student loans and the prospect of a full time job to think about, I would be utterly devastated if I wasn't able to make it on time.
All of my hard work - the phone interviews, US housing fees, visa applications (as well as the visa fees), flights, insurance and much more - would have been a waste of time.
British Airways isn't even an airline I would usually fly with, so this has come as a bit of a shock. Especially, after I've just only stopped panicking about the Iceland volcano.
I just wanted to do something different and I am still so excited about going to work in New York! I just hope that the BA strike is resolved very, very soon.
MARK BECKETT, ST ALBANS
I have a BA flight to Oslo on 27 May to attend the Eurovision Song Contest.
It doesn't look hopeful with volcanoes and Unite conspiring against me.
It is the first time that I have decided to go to Eurovision - after many years of watching the contest, since first seeing Michael Ball and then Sonia represent the UK in the early 90s.
My ticket for the second semi final on Thursday is 775 Norwegian Kroner and I will not be getting a refund for this.
However my main disappointment is that I applied for fan accreditation and have managed to be one of the lucky few people in Europe who has got this - they only issue these to 390 people throughout the 39 countries taking part.
Accredited fans have access to a dedicated fan area, meet-and-greet sessions; open rehearsals and access to opening and after parties.
PETER JONES, CHINA
Peter Jones is worried he won't see his children and girlfriend
I am currently working in China and by the time I get to come home again it will be over seven weeks since I have seen my girlfriend and children.
My partner is a teacher so it will be half term and obviously my children will also be on half term too.
I planned my trips so that I could be home during these times to visit them as it maximises my time with them. My flight home is on 29 May, and I can't see why this won't be affected. My return to China is on 7 June which is in the middle of one of the strikes.
During the last strike action, although I managed to fly home, the flight had restrictions and we were thanked for being tolerant.
Tolerance doesn't come into it - we had no choice!
I have no sympathy for the BA strikers at all - they should be ashamed of themselves. I have always been a big fan of BA but this action, if it affects my travel home, will see me leaving them for good.
I travel about ten times a year and will always do what I can to fly with BA - it's only small business to them, but to me, having the right airline - one who you can trust and depend on - is much more important.
JILL TODD, NEW YORK
Jill Todd flies weekly and is 'struggling to stay loyal'
I fly on business almost weekly and am struggling to stay loyal to BA in all of this.
In the past four weeks I have worked in Paris, Basle, Dusseldorf and New York. I was in California and Madrid last month.
I cannot afford to let my business be disrupted.
But the crews have been misled and do not realise that the further they go with it the more parlous the state of the company becomes.
Everyone is adjusting their costs right now and to stay ahead of the game things change. We are not in the golden age any more.
There aren't many British industries of that scale operating in the global environment. Please don't destroy it.
MORE OF YOUR COMMENTS ON THE BA STRIKES
My partner and I are flying to USA for the birth of our first grandchild. Our flights have been arranged eight months ago. These planned strikes will affect both our outbound and inbound journey. We are gutted that after all this time these two organisations have not sorted this. I will NEVER fly BA again.
Carole Bates, Heddon on the Wall
I am a cabin crew member with BA and I totally disagree with the strike action. The union will cause more financial strain onto BA, meaning less money to pay staff and possibly causing them to go out of business, then thousands will be out of a job. What will the union do then, pay us all our regular wage?
I have mixed feelings about these strikes. I'm supposed to be flying to the States on 19th May to go to a wedding, so from that point of view I hope the dispute will be resolved quickly. However, as a trade unionist, I feel that if the strikes have been properly called then the staff have a right to take industrial action. It's a dilemma.
Janis Murfet, Ely, England
I am a BA staff member (ground forces) and I am sick and tired with the crew being little babies and throwing the dummy out of the pram. Myself and colleagues as well as passengers rely on holidays for a little bit of R&R, and the crew are threatening this. Myself and others have decided that this action may well indeed finish the airline off. They are struck with tunnel vision and this WILL affect jobs on the ground and around the company. Why should crew be so special? We agreed to pay freezes and less working conditions, who gave crew the right to be better? If they don't like it, leave. BA aren't forcing you to work!
Michael Smithe, Uxbridge
I am due to fly out to Italy on the 24th May to get married. These strikes will mean many of my guests will be unable to make the wedding and we may possibly need to drive. When we booked the flights nearly a year ago, we went with BA as we thought it was a name we could trust - obviously not! I think the cabin crew and unions need to grow up and join the real the world. The management team at BA are just trying to save a failing business and their own staff need to understand this.
I have saved for nearly two years now for me and my partner to holiday in Thailand. In the last five months a volcano has worried us, Thailand riots have worried us and now BA has ruined our holiday. Due to fly 28th May into Bangkok - ruined! Do BA staff know that everyone in the country is in the same boat as them in their workplace? My company had a 45% staff redundancy last year and has frozen pay and benefits. All they are doing is dragging BA down. There must be thousands of people that cant afford to re-book or move their holiday dates. They have no compassion.
Robert, Sutton, Surrey
As a business user I am no longer able to justify using BA for flights as I have already had two trips cancelled this year due to industrial action. The crew appear to be better paid with better benefits than most other carriers. All they will succeed in if they continue with the strikes is reducing BA's appeal to travellers which from a business perspective would result in long hall and short hall being separated and pulling out the short hall market and giving to Iberia or running from abroad.
My partner works for BA as flight crew. He, and other BA staff, find it laughable that Unite are telling the cabin crew the things that they are. BA cabin crew work amongst some of the very best pay and conditions in the industry, and yet they are still not happy? Do they want the company to go under? Then they'll be out of a job, and will realise that travel perks don't matter when you don't have a job.
